I've written a few plugins that add buttons to the userbar? If so, there are a few discussions about 3 weeks ago that might be helpful that I participated in regardong adding tabs which is very similar.

The link you provided sends us to an unanswered discussion. Was that the intention?

I am also trying to add a new custom link to the Navbar in Jive 5, and am finding it difficult to find any detailed instructions on how to do this. I am finding not much up to date info on this sort of thing.

2) For dynamically generated menu items, you could substitute the globalNavBar bean by replacing it with your custom navBar implementation in the spring.xml file in your custom plugin. This custom navBar Implementation would need to extend com.jivesoftware.community.navbar.impl.GlobalNavBarImpl. You can then override that navBar's setLinks method and (for example) add your additional menu items before calling setLinks on super.

Depending on the level of manipulation, you may be able to do it with JS/CSS; however, there are use-cases where the core Java elements are needed. This topic has been discussed more recently, How to: Add a Tab to a Place . While this isn't a NavBar Button...all the steps are relevant and relate. This information plus Andreas Ley post above should get you in the ballpark. Let me know if there are still questions. =)
